Line, golden, from this poet? (8)
I believe the answer is:
laureate
'this poet?' is the definition.
(thesaurus)
'line golden' is the wordplay.
'line' becomes 'l'.
'golden' becomes 'aureate' ('aureate' can be a synonym of 'golden').
'l'+'aureate'='LAUREATE'
'from' acts as a link.
(Other definitions for laureate that I've seen before include "Nobel winner" , "One honoured for outstanding achievement" , "Outstanding achiever" , "Person honoured for great achievements" , "This poet writes for English state occasions" .)
